在RHEL6配置IPv6 DNS Server

Youtube上有一个视频是关于IPv4 DNS Server配置的，链接为https://www.youtube.com/watch?v=ZQkMYWTx28o。我在这里照猫画虎，配置一下IPv6的

以本人的机器为例，网卡为eth3，IPv6地址就选2000::ffff

[root@lenovo-m8400-01 ~]# uname -r
2.6.32-431.el6.x86_64

[root@lenovo-m8400-01 ~]# ifconfig eth3
eth3      Link encap:Ethernet  HWaddr 00:1B:21:21:CF:DD  
              inet6 addr: 2000::ffff/64 Scope:Global
              inet6 addr: 2000::21b:21ff:fe21:cfdd/64 Scope:Global
              inet6 addr: fe80::21b:21ff:fe21:cfdd/64 Scope:Link
              UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
              RX packets:100318 errors:0 dropped:0 overruns:0 frame:0
              TX packets:150174 errors:0 dropped:0 overruns:0 carrier:0
              collisions:0 txqueuelen:1000
              RX bytes:19520814 (18.6 MiB)  TX bytes:101293129 (96.6 MiB)
              Interrupt:19 Memory:f7da0000-f7dc0000

1. 修改ifcfg-eth3

    # vim /etc/sysconfig/network-scripts/ifcfg-eth3

     添加 DNS1=2000::ffff

2. 修改/etc/hosts

    # vim /etc/hosts

    添加 2000::ffff    lenovo-m8400-01.example.com    lenovo-m8400-01

3.
